Abstract

The invention discloses an arthrobacter with aerobic denitrification capability and application thereof and belongs to the technical field of microorganism application. The arthrobacter DYS3-4 with aerobic denitrification ability is preserved in the China Center for Type Culture Collection, the preservation date is 29th, April, 2015 and the preservation number is CCTCC M 2015 264. The arthrobacter DYS3-4 can be applied to nitrogenous effluent biological denitrification, mariculture nitrite removal, freshwater aquaculture nitrite removal and low temperature denitrification microorganism preparation. Under an aerobiotic condition, the nitrate and the nitrite in the water environment can be rapidly and effectively removed. The arthrobacter growth temperature scope is wide, the denitrification effect at the temperature of 10-35 DEG C is good, and the arthrobacter has good application prospect in the nitrogenous effluent biological denitrification and the freshwater aquaculture nitrite removal.

Description

technical field

[0001] The invention belongs to the technical field of microorganism application, and in particular relates to an Arthrobacter sp. DYS3-4 with aerobic denitrification ability and its application. Background technique

[0002] In natural water bodies, nitrogen exists in nine different valence forms from -3 to +5. Under the joint action of biotic and abiotic factors, they are continuously transferred and transformed in the water body, forming a complex dynamic cycle. Among them, ammonia nitrogen and nitrite can lead to acidification and eutrophication of lakes, rivers, and offshore oceans. At the same time, as potentially toxic inorganic nitrogen compounds, they also have a toxic effect on aquaculture organisms. How to remove nitrogen pollution in water economically and efficiently has become a key research content in the field of water pollution control.

[0003] At present, the methods used in denitrification of water body mainly include physical method, che...
